Osmotic Energy Storage | Pani Site



The original research group for Pani Energy brought together academics and industry professionals to solve difficult but high impact problems. The research for the group was grounded on tackling climate change with profitable and scalable technologies for the energy and water industry. The Kaya Identity is a general formula for global CO2 emissions dependent on four factors: human population, GDP per capita, energy intensity (per unit of GDP), and carbon intensity where they noticed 2 core traits. 





Kaya Identity - Global Carbon Emissions


The first trait is the world's population is rising and expected to continue. Second, emerging economies such as India, China, and Brazil are experiencing high growth, leading to higher GDP per capita. As more people rise out of poverty there will also be an increase in the need for renewable energy sources. The two pillars that provide a high impact opportunity to tackle climate change are improving industrial efficiencies to reduce the worlds total carbon emissions. Pani's commercial arm is focusing on reducing the costs and carbon emissions of these industrial infrastructures by improving efficiencies with Pani Digital and ADT. Improving efficiencies with Pani Digital and ADT, while the R&D division of Pani Energy is focused on reducing the carbon emissions of the world's population by lowering the adoption barriers of renewable energy. Pani is working in partnership with the University of Victoria to tackle one of the biggest challenges in energy by using its expertise in water, membrane processes, and optimization.



Most renewable energy is intermittent - wind doesn't always blow and the sun isn't always shining. The gap in the intermittent supply of renewable energy to the continuous demand of energy is one of the biggest hurdles towards transitioning to a clean energy infrastructure.



What Are The Options?

When energy storage is mentioned, lithium batteries, flywheels, heat energy storage, or pumped hydro may come to mind. To date, pumped hydro energy storage accounts for over 96% of the worlds grid-connected energy storage systems in terms of rated power output, whereas lithium batteries are less than 1%.

Pumped Hydro Popularity is Rising










But there are only so many hills


Over the past 35 years, an average of 4 new pumped hydro plants has been commissioned each year. The demand for pumped-storage is expected to grow, but suitable locations for large reservoirs in mountains and hills are shrinking. 



How It Works

Take a look at the quick video below to see how OES works.






















Tech Comparison

Pumped Hydro

  • Uses gravitational potential energy between reservoirs

  • These reservoirs require an elevation difference to work

  • Geographically constrained


Osmotic Energy Storage

  • Uses chemical potential energy between two tanks of brine and desalinated water

  • Tanks holding brine and water do not require an elevation difference

  • Geographically unconstrained
